Elicitors: impact on the fungal pathogenicity and colonization in fruits

Fruit rotting caused by filamentous fungus is a serious global issue affecting both economics and food safety. Therefore, effective strategies to combat the occurrence of filamentous fungi in fruit are required. Elicitors, for example, have been demonstrated to improve the physicochemical, nutritional, and functional quality of fruits, making them desirable for controlling fungal colonization and mycotoxin production. In this review, we will first explore the problem of fungal colonization in fruits, as well as the primary control measures. Second, research into the effects of the most important elicitors on fruit quality has been conducted. Finally, the most current studies on elicitors’ influence on fungal growth, as well as their primary routes of action, are discussed. We can conclude that while there is evidence that elicitors can reduce fungal pathogenicity and mycotoxin formation, more in vivo research is needed to assess their efficacy in various fruit types and conditions. •Chemical elicitors have a positive effect on fruit quality.•Recent advances in controlling fruit fungal pathogens using elicitors were discussed.•Elicitors reduce the pathogenicity of fungi and their colonization of fruit.•Elicitor action on toxigenic fungi and their mycotoxins requires further research.
